The Dow started sinking after the Fed's Philadelphia branch reported a manufacturing slowdown resulting from a steep drop in companies' orders. It only got worse, as the index ultimately lost 250 points to close at 12,573, a 2 percent drop.

A trader works on the floor of the New York Stock Exchange, Thursday, June 21, 2012 in New York. A quiet start on Wall Street quickly turned into a rout Thursday as the Dow Jones industrial plunged 251 points, the second-biggest drop this year.

Relentlessly gloomy reports about the health of the world economy rocked Wall Street on Thursday, stirring more worry about the stalled recovery and sending the stock market to its second-worst decline this year.

The bad economic reports kept piling up: Manufacturing slumped in China. A closely watched unemployment figure jumped to its highest level in nine months. Sales of previously owned homes fell. Then came word of a sharp contraction in Northeast manufacturing, the worst since last August.

Suddenly, the outlook turned so bad that a Goldman Sachs analyst told clients to place bets against the stock market.

The Dow started sinking after the Philadelphia branch of the Federal Reserve reported a manufacturing slowdown resulting from a steep drop in companies' orders. Then the losses just accelerated.

Mining and other companies that made basic materials fell hard after prices for commodities such as copper and oil dropped.

Elsewhere, the Labor Department reported that the four-week average of applications for unemployment benefits jumped to the highest level since September. The National Association of Realtors also reported that sales of previously owned homes dropped 1.5 percent in May.

All this unfolded a day after the Federal Reserve slashed its estimates for U.S. economic growth and said it would extend a bond-buying program through the end of the year. The moves disappointed investors who had hoped for bolder steps from the central bank to get the economy going again.

"What's worse is that things are getting weaker without the Fed coming in," said Rex Macey, chief investment officer at Wilmington Trust Investment Advisors. "We had a run-up in the market this month because people had been expecting Fed action. Today, the market is giving it back."

The Dow lost 250.82 points to close at 12,573.57, a drop of 2 percent.

The Standard & Poor's 500 index lost 30.18 points to 1,325.51, a decline of 2.2 percent. The Nasdaq composite fell 71.36 points, 2.4 percent, to 2,859.09. All three indexes lost their gains for the week.

The report on slowing manufacturing in China was troubling since that country has helped drive global economic growth over the past four years. China is a major importer of copper and other basic materials.

A manufacturing survey for countries that use the European currency also showed a contraction. That report, together with the China slowdown, helped sink commodity prices. Copper and platinum fell 2 percent.

The only good news was apparently at the pump. The price of oil fell Thursday to its lowest level in almost nine months — $78.20 a barrel. Gasoline was way down, too, at $3.47 a gallon, 46 cents below its peak in early April. Experts say it could dip to $3.30 by July 4th.

The Philadelphia Fed index pushed Treasury prices up and yields down as traders shifted money into their favorite hiding spots. The yield on the 10-year note slipped to 1.61 percent, down from 1.63 percent late Wednesday.

Material and energy companies, whose fortunes are closely tied to economic swings, led all 10 industry groups within the S&P 500 index lower. Just 12 of the 500 companies in the index rose.

In Europe, auditors calculated that Spain's troubled banks need as much as €62 billion ($78.76 billion). A Bank of Spain official said that scenario was much less than the €100 billion that the 17 countries in the euro currency union said they would provide for Spain's banking sector.

All day, speculation swirled that some major banks would have their credit ratings downgraded. After the market closed, Moody's Investors Service lowered the ratings of 15 the world's largest banks, including Bank of America, JPMorgan Chase and Goldman Sachs, saying their long-term prospects for profitability and growth were dimming.

However, with interest rates already at rock-bottom levels, the downgrades may not affect the cost of funding for the banks that much.

— Bed Bath & Beyond plunged 17 percent, the most in the S&P 500. The retailer said it expects weaker earnings in the current quarter than analysts expected even though it reported better profits after the market closed Wednesday. Bed Bath & Beyond stock lost $12.50 to $61.17.
